Welcome to this edition of The Intelligence Brief… This week, astronomers continue to unravel the mysteries of the interstellar comet 3I/ATLAS, whose latest observations have revealed a host of new anomalies that defy expectations. In our analysis, we’ll explore 1) how Keck Observatory data confirm the presence of an unusual “anti-tail” and a nickel-rich, iron-free gas […]

A new paper on the interstellar object 3I/ATLAS (accessible here), reports data taken by the Keck II telescope in Hawaii on August 24, 2025, when 3I/ATLAS was at distances of 2.75 and 2.6 times the Earth-Sun separation (AU) from the Sun and Earth, respectively. As with the Hubble Space Telescope image obtained on July 21, 2025 (analyzed here and here), the […]

Interstellar comet 3I/ATLAS will soon encounter two spacecraft on a journey towards a Jovian moon and an asteroid system. Photograph: (Gemini Observatory/ Chile) 3I/ATLAS update today: Another window to study the interstellar comet opens around October 25. Two probes travelling towards a moon of Jupiter and an asteroid system might tear through the comet’s tail and […]
